The present invention relates to the technical field of activated clay production methods, designed to eliminate acidic wastewater and reduce general wastewater. The method comprises the following steps: 1. mineral processing; 2. solid-phase activation at room temperature by extrusion using acid and water; 3. drying and pulverization; and 4. finished product testing and packaging. This method offers the advantages of being pollution-free, low-cost, and simple to operate, making it suitable for widespread application.
Description
Technical field
The present invention relates to the method for producing active clay technical field.
Background technology
Account for certain status, widely used atlapulgite in national economy, not only production history is long, market position is firm, and still is in the stage of continuous rising.But the manufacture craft of present atlapulgite is as shown in Figure 1, and no matter domestic or external, do not make substantial progress decades, its expensive, poor benefit, and production process in serious acid pollution, restricted the development of this product and applied.Especially in the current environmental protection epoch, with great strength and vigour sour water is handled and discharging in the activated clay production process, forces the thin enterprise of part capital for want of to administer the enormous expenditure of sour water and haves no alternative but close, stop, change.Chinese patent also has the technology report of this respect.As the patent No. is that 90101333.1 activation of swelled ground, the patent No. are the production method of high-effect and activity clay by semi-hydrometallurgy of 90105982.X, its reaction adopts compressive reaction to improve the quality and the decolorizing ability of atlapulgite, does not still solve the sour water pollution problem preferably.And increase the production cost and the operation easier of reactor to a certain extent.
Summary of the invention
The object of the present invention is to provide the no acidic sewage discharge of a kind of Production Flow Chart, realize the method for producing active clay that CR production, production cost descend greatly.
Technical scheme of the present invention is to realize like this.This method for producing active clay is characterized in that steps in sequence is: 1, ore dressing; 2, add acid and water and carry out the activation of extrusion molding normal temperature solid phase, above-mentioned sour add-on is required activated bentonite 1-3% mass percent, be benchmark with the need activated bentonite, and the concentration of acid is with mass percent concentration 98%H
2SO
4Calculate; 3, drying is pulverized; 4, finished product detection, packing.
Above-mentioned acid is sulfuric acid, hydrochloric acid.
Its comprehensive production cost of the carclazyte that this production technique provides descends greatly, and the rate of profit of this product is brought up to more than 30% by about 15% of routine, and promptly the industrial profit rate is enhanced about more than once.See the production cost comparison sheet.
Production cost relatively
One ton of atlapulgite finished product of every production prime cost contrast table
| Sulfuric acid (kg) | Coal (kg) | Electricity (degree) | Water (degree) | Man-hour | Waste water control | |
| Traditional technology | 150-250kg (general) (height) | About average 300 Kg | About average 100 degree | About average 100 degree | In traditional technology is " 1 " | Need |
| Xin Xin skilled worker's art skill | 40 60kg (general) (height) | General: substantially need not or a small amount of high: 100,000 | General: high about 20 degree: about 50 degree | About 20 degree | Novel process needs about 0.5 approximately | Do not need |
General: common atlapulgite.
High: high-efficient activated clay.
And do not have sour water discharging in the Production Flow Chart, and be its PH of common waste water 〉=6, realized CR production, not only can administer expense, and solve the environmental issue that makes the headache of enterprise for enterprise saves a large number of blowdown.
Its technology theory is according to Huffman ion sequence, hydrogen ion comes the foremost, even with under the isoconcentration, hydrogen ion also can get off calcium ion-exchanged, but consider various secondary reactions and other factor, we only need two to the hydrogen ion that is four times in calcium ion, and it just can get off calcium ion-exchanged, in the actually operating, after to the flow measurement of need activatory wilkinite cationic exchange, quantitatively add hydrogen ion amount, be equipped with the appropriate reaction condition again, just can realize the activatory purpose times over calcium ion.This by the sulfuric acid calculating of 98% content, in theory only needs the 1-3% of original soil amount just passable times over the hydrogen ion amount of calcium ion.

Embodiment
Below in conjunction with description of drawings embodiments of the invention are further described:
The production method of embodiment 1, common atlapulgite, no specified otherwise is mass percent, benchmark is for needing the activated bentonite quality.
(1) ore dressing;
(2) adding mass percent concentration is that 98% sulfuric acid and water carry out the activation of extrusion molding normal temperature solid phase to wilkinite, and promptly sulfuric acid, water, bentonitic three's mass ratio are 3%: 30%: 1, are benchmark with the wilkinite quality;
(3) dry then, pulverizing;
(4) finished product detection, packing.
Claims (2)
1, a kind of method for producing active clay is characterized in that steps in sequence is:
(1) ore dressing;
(2) add acid and water and carry out the activation of extrusion molding normal temperature solid phase;
Above-mentioned sour add-on is required activated bentonite 1-3% mass percent, is benchmark with the need activated bentonite, and
The concentration of acid is with mass percent concentration 98%H
2SO
4Calculate;
Above-mentioned water add-on is an activated bentonite 30-40% mass percent, is benchmark with the need activated bentonite;
(3) drying is pulverized;
(4) finished product detection, packing.
2, production method as claimed in claim 1 is characterized in that the identical normal hydrochloric acid of described acid employing replaces sulfuric acid.
